Should print exactly as shown in your browsers print preview. CB has no specific print styling being applied to output only URLs. That's normally due to CSS being applied to @media print. Your Joomla template maybe applying CSS to output the links, but it normally does that after the image instead of replacing the image. The CSS for such usages is usually something like the following.
Code:
@media print {
a[href]::after {
content: " (" attr(href) ")";
}
}
I know for sure Joomlas protostar template applies the above.
